Butter and flour an 12″ x 18″ x 1″ baking pan. I like to use foil for ease of getting them out. In a heatproof medium bowl set over a saucepan of simmering water, heat butter, chocolate chunks and unsweetened chocolate until melted and smooth. Set aside and allow to cool slightly.

In a large bowl, stir together eggs, coffee, vanilla and sugar. Blend chocolate mixture into egg mixture and allow to cool to room temperature.

In a medium bowl, whisk together 1 cup flour, baking powder and salt. Add flour mixture to chocolate mixture. In a medium bowl, toss together Oreos and remaining 1/4 cup flour. Add Oreo mixture to chocolate mixture and gently fold to combine. Pour batter into baking pan and smooth top with a rubber spatula.

Bake 28-35 minutes or until a toothpick inserted 3 inches from center comes out clean with some crumbs attached; do not overbake. Allow to cool completely. Refrigerate to get clean cuts.

Oh my -- I just made these brownies and they are divine!! I love that they make a gigantic batch so we can have now and freeze the rest. Lining the pan with foil rand chilling the brownies really helps with easy removal/cutting. Fabulous recipe. Thanks so much!

This recipe came just in time for our super bowl party, can't wait to try them. I love your blog. We are in the process of setting up one for our rental home and have been unable to insert the weather link as you have, any suggestions?

Joe, this is just the recipe I needed! A teacher at my school has requested either fudgy brownies OR an Oreo cake for her birthday next Monday...now I can get all her favorite things in one dessert! Thank you! :)

You know, I have made these quite a few times since you first posted the recipe...but I forgot about them! Thanks for the repost...I have to take a dessert to a friend and this is the perfect(!!)dessert for her!
